Problems solved by technology

However, low-molecular-weight silicone polymers are easy to emulsify, but have poor migration resistance and poor durable waterproofing of the coating; while high-molecular-weight silicone polymers are difficult to emulsify, and the emulsion particles are coarse, which is difficult for ultra-deep penetration and also affects the coating. Durable waterproof performance

Abstract

A water-proof water-base microemulsified material for building is prepared through modifying the organosilicone polymer containing active group with-sulfuryl chloride containing hydrophobic group under the action of catalyst, adding emulsifier and emulsifying assistant to water, and microemulsifying in water.

Description

1. Technical field [0001] The invention relates to a microemulsion water-based building waterproof material and a preparation method thereof, belonging to the field of polymer modification and preparation of waterproof materials. 2. Background technology [0002] Common waterproof materials can be divided into five categories: modified petroleum asphalt; polymer membranes; polyurethane or acrylic membranes (solvent-based); Butadiene rubber, styrene-butadiene rubber, nitrile rubber emulsion, etc. Polyurethane or acrylic solvent-based membrane materials have been banned by the state due to serious environmental pollution; modified petroleum asphalt has less and less market share due to its high pollution and poor weather resistance; Waterproof substrates have high requirements for flatness and shape, and the application process is complicated and time-consuming; organic fluorine compounds have excellent waterproof performance, but are expensive. For example, FX-3573 and 3587 ...
